I would suggest that following tragic accidents the time between the loss of a friend(s) and the report of the cause(s) being released is best used remembering the good times had with that person(s) no longer with us ......Speculation...rumours..guesses or whatever you want to call them serve no purpose in written form other than to revive moments of sadness for those that knew them...
Yes Prune is a rumour network...rumour about things that dont affect others emotionally..
I may be wrong but just my view on dignity and human respect for others
